    The Other Big Meltdown

    By Laura Allen Posted on 12.19.2008 20 Comments

    To predict the unpredictable: That’s the goal of a new government initiative on abrupt climate change. As the atmosphere reels under the influence of greenhouse gases, scientists fear the growing risk of dramatic environmental changes occurring within decades—far faster than current computer models predict. Ice sheets might not just melt but collapse wholesale, rapidly raising sea levels and flooding entire coastlines. Regional rain shortages could cause megadroughts that choke our water and food supply.

    It's a little ironic that people like Mike, who supported Mrs. "ABORTION IS EVIL, GOD CREATED THE EARTH IN 7 DAYS!" Palin, are trying to talk science. You all realize climate really CAN'T be measured on a year to year basis? You realize that this year's temperature is still among the highest temperatures we've EVER recorded? Minor fluctuations should be expected, since we're only examining the WEATHER on a year to year basis. Ever heard of the La Nina effect? Yeah. The vast majority of the scientific community supports the idea that humans are contributing to climate change. They have the data. The brightest minds in the world are ALL in support of this, with the exception of a few (and PopSci has no obligation to waste time and space on a tiny fringe group with no credibility). Who am I to believe? The experts and what the data points at? Or a bunch of random conservo-crackpots on the internet who don't have any qualifications whatsoever? The only thing you people are capable of typing out is "it's a conspiracy" whenever conflicting evidence comes out, that somehow the wider scientific community is pure evil and trying to do this all for greed. Pleaaase.

    Baby Steps Going Out of Style

    By Rachel Durfee Posted on 12.2.2008 5 Comments

    Common wisdom dictates that in order to learn a complicated skill, it is best to break the skill down into parts, conquer simpler steps first, and then incrementally move forward, eventually getting to the hard stuff. For example, you don't just tackle a multivariable equation, you start with easier examples. First, you learn to add, subtract, multiply and divide. Then, you learn how to solve 2x=8, then x + y = 7, and so on and so forth until you are aptly equipped to solve 2(5x + z) = 30x + 3y + 10.

    In general, East Asian countries outperform the US in math, and no, it's not because we go to school for 16 hours a day. I don't know who told you that school days were like that, but that's an outright lie. We do have class on Saturdays though, but that's barely for 4 hours. The issue of 'length of study' is not important. The solution is not to force kids to practice hour after hour. That puts way too much stress on a child, and first hand experience tells me that I would NEVER allow someone else to go through that kind of schooling (we do have the highest suicide rates for students in the world for a reason). It's got nothing to do with the culture of a country either, it's got everything to do with the schools themselves. To the above poster, you are right, the US education system is out of tune. Friends who got straight C's in my school went on and got 5.0 GPAs in American schools. Why? It's too easy over there. This is not a problem of quantity of work, it's quality. The only thing that will save American schools is reform from the very top - better teachers, better facilities, more books, and whatever else a good school needs. A new teaching style isn't going to cover for the inadequacies of the very foundations of the educational system.

    Farming in the Sky

    Isn't this a little too... radical? We're still producing an enormous surplus in food. The only reason there are starving people is because of corruption, war, and the other host of problems in developing countries. I might not have any figures, but I'm positive that only a minority of countries in the world are using the most modern techniques to farm efficiently. Instead of getting the rich to race ahead in farming technology, we could just try getting the poor caught up with the rest of us.
